JBA header install
Question is about the passenger side header. All the write ups i've seen say the Y-pipe needs to be removed, and mine can't be removed as it's welded to the LM1 I-pipe. The drivers side has a flange to remove the down pipe but there is no flange on the passenger side.
So..
Do I try and replace them from the top
Cut the pipe and put a clamp on til I can get to a shop
Just clamp it and leave it
any and all suggestions welcome (I think)
